Spring Runoff is Older Than You Think

Spring Runoff is Older Than You Think

DRI’s Rosemary Carroll, Research Professor of Hydrology, co-authored a new study that found spring runoff in mountains across the Western U.S. is much older than previously known. Using advanced dating techniques, the research discovered that melting mountain snowpacks first replenish groundwater reserves before filling springs several years later. This means that the water relied on by communities across the West takes over five years from snowflake to streamflow. The research has implications for water management and our understanding of the changing dynamics of water availability.

New Study Finds Rocky Mountain Snow Contamination

New Study Finds Rocky Mountain Snow Contamination

An examination of Rocky Mountain snow finds higher contamination levels of mercury and others metals in the northern part of the range, consistent with increased current and historical mining in the region. The study, published in the May issue of the journal Environmental Pollution, examined contamination levels for Mercury, Zinc, Cadmium and Antimony from nearly 50 sites in the Rocky Mountains.
